2. Determine your barcode scanning needs
Choosing the right barcode scanner for your business requires a clear understanding of your specific needs and operational environment. It also means assessing the different types of scanners available to find the right fit for your budget and operations.
Start by answering these questions:
- What kind of workflows (retail, warehousing, postal, travel, etc.) will you be scanning in?
- What type of barcodes (symbologies) will you be scanning?
- How many scans per shift, or per task, will you perform?
- Do you need to scan multiple barcodes (batch scanning) at once?
- What physical conditions (long distances, awkward angles, physical labels or digital displays, torn or obscured barcodes, etc.) must the scanner accommodate?
- What type of environmental conditions (lighting, dust, etc.) may impact scanning?
- Do you require a portable cordless or fixed/corded scanner?
- Do you have existing devices that barcode scanner software can run on?
- Do you have development resources to build and deploy a new solution?
Based on your answers, you can identify the basic barcode scanner requirements using this table:
Criteria | Description |
|---|---|
Form factor | Between hardware and software options, choose the form factor (corded vs. cordless, handheld computer vs. smart device, etc.) that best fits your work environment. |
Speed | Your solution must decode information quickly and efficiently, enabling rapid data capture and less frustrating user experiences. This applies to single and multiple barcode scanning. |
Accuracy | Measured as the number of false positives (captures of label data that don’t exist) and incorrect data over a series of captures. This is heavily influenced by scanning conditions, as barcodes can be smudged, scratched, or compromised by poor lighting and awkward scan angles. You should aim for lower rates that match the speed of your desired workflow. For example, customer self-scanning may require only one accurate scan over several minutes, while a warehouse worker may scan thousands of labels per shift. |
Symbology support | Data requirements and industry standards determine which barcode symbologies your scanner must support. These requirements often change as your business scales. For example, an inventory tracking app for a small store may only require 1D barcode support (e.g., UPC codes), while a global retailer would need to add support for 2D barcodes (e.g., Data Matrix and QR codes). |
User experience | The effectiveness of a barcode scanner is significantly affected by its UX design. Easy-to-use interfaces, relevant feedback, and quick response times are essential for minimizing scanning errors and improving user adoption rates. |
Security and privacy | Barcode scanning software typically accesses device cameras and handles sensitive data, making strong security and privacy practices critical. Certain industries also require scanners to comply with security and privacy regulations, such as GDPR, PCI DSS, and HIPAA. |
Offline operation | Scanners that can operate offline are ideal for environments such as large warehouses or remote locations with spotty or no internet connections. |
Device compatibility | Software scanners must be compatible with your device operating system, such as iOS and Android, and integrate seamlessly with other applications. |
Ease of integration | Many barcode scanning systems offer SDKs (Software Development Kits) and APIs (Application Programming Interfaces). Ideally, these should fit into your existing development stack and make integration with existing applications and systems easy. |
Advanced features | Modern software barcode scanners can do much more than just scan single barcodes. For example, batch scanning multiple barcodes at once can increase efficiency by a factor of 10. |
AI assistance | Newer SDKs offer AI-enabled barcode scanning and augmented reality (AR) overlays, improving speed, accuracy, and real-time insights such as stock levels and whether on-shelf prices are correct. |

The following table identifies the desirable barcode scanning features by industry.
Industry | Key desirable features | Common scanner types |
|---|---|---|
| Handheld smart devices, cordless laser, and stationary omnidirectional scanners are common, offering quick scanning from various angles to reduce scan times. | |
| Portable data terminals and smart devices equipped with barcode scanning SDKs are ideal, as they're easier to move around the facility. | |
| Smart devices with scanning software are often deployed to match existing device fleets — lowering production and maintenance costs. | |
| Smart devices equipped with scanning software are gaining acceptance as they offer the performance and feature flexibility to suit different manufacturing workflows. |
4. Make the final decision
To make the final decision on your barcode scanner, evaluate how each solution performs in your environment and with your users.
Once you've found the solutions with the features necessary for your environment, perform these final steps:
- Conduct real-world trials in the field: Run pilot tests of each solution under different scenarios, including degraded conditions. Read our complete testing guide for a detailed walkthrough of real-world performance testing.
- Calculate the total cost of ownership (TCO): Beyond the initial purchase price, development effort, and annual licensing costs, there will be ongoing maintenance and support costs.
From here, you can go from acquisition to operation with greater confidence that your barcode scanner will succeed!
What is a barcode scanner?
The core components of barcode scanners include:
- Light source: To read a barcode, it has to be adequately lit. Historically, scanners have included a light source component (such as a red light, laser, or LED) to achieve this. However, today's combination of barcode scanning software and devices is powerful enough to work effectively with ambient light, even in low light conditions.
- Sensor: A sensor detects the light reflected back from the barcode. In laser scanners, the sensor captures the reflection of a laser beam across the barcode, then converts this light into an electrical current. In camera-based and charge-coupled device (CCD) scanners, like those used with smartphones, the sensor is an imaging component that captures an image of the barcode.
- Decoder: The decoder interprets the sensor’s data, converting the barcode’s black and white spaces into text. The decoder uses specific algorithms to decode the data correctly and apply error correction techniques to ensure the data is accurate.
What are the different types of barcode scanners?
There are two main types of barcode scanners:
1. Hardware barcode scanners
These are physical devices that can range from handheld units to stationary industrial models (like a grocery scanner).
These types of machines use optical sensors or light beams plus built-in software to capture and decode the visual patterns on barcode labels. They come in a fixed form factor and run software with a limited set of functions.

2. Software barcode scanners
These are downloadable applications or SDKs (software development kits) that transform the cameras on smart devices (such as smartphones, tablets, or handheld computers) into effective barcode scanners. As processors and camera sensors increase in speed and flexibility, these image-based systems can meet or exceed the speed of the fastest laser scanner.
Software-based scanning solutions are also highly versatile and can integrate with other device apps and enterprise systems, such as inventory management and point-of-sale operations.
